Compact Differential Pressure Transmitter

Shanghai Zhaohui Pressure Apparatus Co., Ltd. is one of the leading manufacturers and suppliers of compact differential pressure transmitter in China, also supports customized service and 1 year warranty. Welcome to wholesale bulk durable compact differential pressure transmitter in stock here from our factory.

Designed for space-constrained installations, this lightweight unit delivers reliable DP measurement with ±0.1% accuracy and quick response. The compact differential pressure transmitter offers 4–20 mA analog output with optional local display, simple push-button zero/span adjustments, and IP67 environmental protection. Perfect for HVAC systems, skid-mounted packages, filter condition monitoring, and pump differential pressure in water/wastewater treatment. The low pressure different pressure transmitter's small footprint, corrosion-resistant wetted parts, and vibration-resistant construction reduce installation costs while maintaining stable performance in tight piping layouts where larger transmitters cannot fit. Both models share common diaphragm materials but differ in processing power, communication options, and physical size to suit distinct application needs.

Compact differential pressure transmitters are widely used in HVAC, filtration monitoring, liquid level measurement, and flow metering. HVAC air handler static pressure, skid-mounted water treatment systems, pump suction/discharge differential, and tight pipe networks. Ideal for filter clogging alerts, chiller flow verification, and small-bore line monitoring where space is limited and simple, reliable 4–20 mA output suffices.

Lightweight, space-saving design with ±0.1% accuracy, 4–20 mA output, various industrial standard signal output. push-button zero/span adjustment, IP67 rating, corrosion-resistant wetted parts and vibration-resistant construction. Simple installation with direct pipe mounting, no external power supply required for configuration, and maintenance-free operation. OEM provided.
